Code Name Causes Possible Solutions Er-16 Inertia ID Error The inertia found by the drive was too small or too large during Inertia Tuning (10% or less, or 50000% or more). Decrease the values set for the frequency and amplitude of the test signals used when doing inertia tuning. First, decrease the test signal amplitude, and then do Inertia Tuning. If the error continues, decrease the test signal frequency and do Inertia Tuning again Correctly set the motor inertia as specified by the motor, and do Inertia Tuning again.
